The second is the directly related manufacturer document used for installation, configuration and engineering verification.
Bearing-housing radial vibration
Holds the reverse-mount probe at a repeatable machine-case depth.
Thrust-position probe installation
Protects the probe cable between the sensing tip and conduit.
Machine-case proximity retrofit
Allows controlled gap adjustment from outside the casing.
Externally accessible probe service
Supports housing renewal while retaining the measuring-point geometry.
Read the applicable Bently Nevada instructions before work. Verify 21000-34-10-20-058-04-02 and the installed 21000 Proximity Probe Housing Assembly configuration.
1
Verify 21000-34-10-20-058-04-02, the two-inch standoff and 5.8 in (147 mm) penetration before work.
2
Place the monitored machine and protection channel in the approved maintenance state.
3
Preserve the 3/4-14 NPT machine-case thread and housing orientation.
4
Record probe gap, sleeve position, cable route and plug arrangement before removal.
5
Protect the probe tip, sleeve bore, O-rings and sealing surfaces from contamination.
6
Match the installed ETR probe, cable and approval option to the documented loop.
7
Secure the sleeve and conduit so mechanical load cannot alter probe alignment.
8
Verify static gap, dynamic response, seal integrity and alarm action after assembly.
Technical notes
